At LEWCO, delivering high-quality products along with providing excellent customer service are top priorities. Customers often take notice of this and continue coming back to LEWCO for their process heating needs. One specific customer, a spring manufacturer specializing in overhead door supply, recently received a shipment of their seventh and eighth industrial conveyor ovens from LEWCO.
The custom conveyor ovens are rated for a maximum temperature of 650°F and are used to stress relieve torsion springs. Both ovens feature a single, direct-fired, natural gas heater-box with a capacity of 1,000,000 BTU’s/HR. A 2,000 CFM circulation fan delivers uniform vertical down airflow throughout the workspace. Some additional features included an exhaust hood on the exit end of the conveyor, spring edge guides on both ends, and a pneumatic actuated dump tray at the infeed end with a manual control valve.
Due to the automation of the customer’s process and integration with their existing equipment, the oven is equipped with a Programmable Logic Controller. This PLC incorporates safety, motion, discrete and drive capabilities into a single controller. The PLC, VFD and temperature controller all communicate over Ethernet IP allowing remote monitoring and process changes from a master control room through the customers HMI. Over the years LEWCO has worked with this customer’s engineers to add various options to streamline functions for their operators as well as data acquisition features to help track process efficiency.
